DEVICE FOR TREATING LIQUIDS.

Specification of Letters Patent.

To all whom, it may concern Be it known that we` Ama-inn O. Fox andR-UssuLL ll. Barns, citizens of the United States, residing atlifadison, in the county of Dane and State of l/Visconsin, have inventeda Acertain new and useful Improvement .in Devices for Treating Liquids,of which the following is a specification.

This invention relates to devices for treatine; liquids, and has for itsobject to provide a new and improved device of this description.

This device may be used to treat any desired liquid by passing a gastherethrough where it is .important that the liquid shall not be'blownover into some other part of the apparatus.

For purposes of illustration we have shown our invention iu connectionwith an apparatus for treating milk and cream wherein air is forcedthrough a liquid and the resultant gaseous product forced through themilk, cream or other material.

i Referring now to the accompanyingr drawings, Figure l is a view inpart section-showing one form of our device; Fig. 2 is a sectional viewtaken on line 2 2 of Fig. -1; Figu 3 is a sectional viewhtaken on line33 of Fig. l; Fig. Il is a View showingr a modified construction.

Like numerals refer to like parts throughout the several figures.

Referring now to Figs. 1. 2 and 3, we have illustrated a receptacle lwhich is in practice partially iilled with the liquid 2. At some pointintermediate the bottom 3 of the receptacle and the surface of theliquid therein is a stationary device 4 for causing intimate Contactbetween the gas and the liquid. This device is fastened in position inany desired manner and is provided with a series of inclined faces 5which extend from the edge toward the center, all of said. faces beingconnected together at the center as shown at 6. The inclined faces maybe provided by forming,lr a series of slits ina piece of 4suitablematerial extending from the outer edge toward the center and thenbending the pieces so asto form the inclined faces. These -inclinedfaces may be formed other manner by pieces separated at their edges soas to form openings through which the gas and liquid may pass. Thesefaces ,are upwardly inclined so ithat as the air passes up through theliquid it will be divided up and will pass along these inclined faceswhich are so positioned as to give the liquid a rotary or circulatorymotion, being directed toward the walls of the receptacle. Located abovethe surface of the liquid and fixed in position in any desired mannerisan obstructing device 7 which has a central opening 8 and an inclinedface 9.v This obstructing device is preferably fastened inside of thereceptacle in any desired manner. The inclined face of the obstructingdevice is preferably in clincd downwardly and inwardly from the pointlwhere taehed to the receptacle, the object being that there shall be anobstructing device which will prevent the passage of liquid which isforced upwardly on or near the inner walls of the receptacle and yetpermit air or other gas to freely pass. In the par ticular constructionshown, this obstructing,r device is illustrated as a hollow invertedfrustum of a cone. The receptacle 1 is provided lwith an inlet ,l0 whichis connected by a suitable pipe or connection 1l with a source of gassupply 12 which in this ease is Ashown as a blower.

[n Fig. 4, we have shown the receptacle 1 with one of the devices 4located beneath the surface oi the liquid and another located.

above the surface of the liquid. The in clined faces of the part 4: mayall be inclined in the saine direction or some of them .may be inclinedin one direction and some in a dill'crent direction. The receptacle ispro- 'vided with an outlet 13 to which is connected a pipe 14 whichconducts the gas to the point desired. The receptacle may be pro- .idedwith a suitable pipe 15 and valve 16 at the bottom for drawing'otl' theliquid yand a suitablepipc 17 controlled by a valve 18 for inserting theliquid in p the receptacle. lt is also evident that the orin ofconstruction and arrangement of the various parte may be varied in manyparticulars without departingr from the spiritlof our invention.

The use and operation of our invention are as follows: When it isdesired to treat the liquid by bringing air or other 'gas in contactwith it, such liquid is placed 1n the receptacle 1 so as to partiallyillsuch receptacle. The air or other gas `is then forced into the inlet l0through the ,liquidiuntlit Patented Oct. 27,1914.

mister/e strikes the part 4. .lt is there divided and its directionchanged by the inclined faces 5, it being directed toward the walls ofthe receptacle and given a more or less circulatory movement, carryingthe liquid with it. vit will thus be seen that the air or other gas isfinely divided and the material agitated and brought into 'intimatecontact with such air or other This agitation tends to cause the liquidto be thrown up so that without our device it will escape ythrmigh theoutlet 13 and pass on to another part of the apparatus where it is notWanted. This is particularly true if the pressure with which the air orother gas is forced into the liquid is comparatively high. This liquidlfollows the inner surface of the receptacle and is either in contactWith such surface or near thereto and is caught by the obstructingdevice 7 and falls back into the main body of liquid. The air or gaspasses freely through the opening 8 in the obstructing device and outthrough the outlet 13 to the point of use. It will be seen that by meansof this device, the air or gas is brought into intimate contact with theliquid and yet the liquid is eflectually prevented from passing out ofthe receptacle with the gas to the point where it will produce aninjurious effect. lt Will further be seen that the liquid is agitatedand thoroughly mixed With the air Without the use of any movableapparatus, the stationary part et accomplishing this result.
